SAD-IRON HEATER.

is a specification.

My invention consists of a heater for sad irons, the same embodying abody, means for supplying highly combustible gas thereto, and means fordischarging the products of combustion from said body whereby they areprevented from entering and thus fouling and heating the work roomoccupied by the heater, provision being made also for directing saidproducts elsewhere for additional use if so desired.

It consists also of details of construction as will be hereinafterdescribed.

The invention is illustrated in the accompanying drawing, but theimportant instrumentalities thereof may be varied, and soit is to beunderstood that the invention is not limited to the specific arrangementand organization shown and described.

Figure 1 represents a side elevation of a sad iron heater embodying myinvention. Fig. 2 represents a vertical section on an enlarged scale onthe line w-00 Fig. 3. Fig. 3 represents a vertical section on the line'yy Fig. 1 on an enlarged scale. Fig. 4: represents a horizontal sectionon the line zz Fig. 3.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings, 1 designates the body of a furnace or heater,in the lower portion of which is the tube 2 with et openings 3 thereinproducing a burner which is supplied with combined gas and air throughthe air intake pipe 4 and the gas intake pipe or branch 5 respectively,said pipe 4 being connected with said burner at the end thereof, saidbranch 5 being connectj ed with said pipe 4: at the side thereof andopening into the same.

(3 designates a pipe for conveyingair from any suitable source to thepipe or tube 7 and from the latter to the pipe 4, said pipe 7 beingconnected at one end wit-h the pipe 6 by the coupling 8, and at theother end with the pipe 4: by the nipple 9, on the latter, said pipe 4having a cook or valve 10 for evident purposes.

11 designates a pipe for conveying gas Specification of Letters Patent.

from any suitable source to the tube or pipe 3 12 and from the latter tothe branch 5, said pipe 12 being connected at one end with the pipe 11by the coupling 13 and at the other air into the body 1 so as to supplythe burner 3 therewith. Rising from said base 15 at opposite sides ofthe inlet 16 are the inwardly inclined or overhanging-plates 17 whichserve to deflect the air entering said inlet toward the jet openings ofthe burner 3 so as to increase the combustion of gas at said opening andintensify the heat thereof.

Within the body 1, near the upper portion thereof is the perforatedplate 18 which extends as a dome in the body and is firmly secured tothe sides thereof, it forming a heat retarding and radiating battle aswill be referred to further hereinafter.

On the upper end of the body 1 is the pipe 19 for the escape of theproducts of combustion from said body, said pipe being connected withthe pipe 20 which latter is con nected with the exhaust pipe 21 anddischarge pipe 22. Intermediate of said pipes 21 and 22 is the suctiondevice 23 for forcibly and effectively drawing the products ofcombustion from the body 1 into the pipes 20 and 21 and directing theminto the pipe 22 which latter opens into the atmosphere, orelsewhere. Idraw in larger quantities of gas in order to produce great heat for theiron and as this results in voluminous products of combustion, I makeprovision for getting rid of the latter as quickly as possible; hence,the said products of combustion are forcibly and effectively withdrawnfrom the body 1.

It will be noticed that there is a plurality of pipes 7 and 12, so as tobe connected with two bodies of heaters and thus supply the lattersimultaneously with gas and air. The pipe 19 is common to said bodiesand each body has a door 24 for access to the interior thereof forremoving the heated iron occupying the stand 14-, or for the purpose ofintroducing the said iron into the body to be heated.

The doors of the plurality of bodies face in opposite directions so thata double gang or shift of laundrymen may be employed, ironing tablesbeing placed on opposite sides of the device, said doors having vents 2F therein to admit fresh air into the body of the furnace above theflames of the burner and below the battle for purposes to be hereinafterdescribed. The air conveying pipe 6 is connected with an air holdingtank 25, the latter being in communication with the compressor 26,whereby the pipe 6 and consequently the burner will be supplied with alarge volume of air, it being evident that gas and air mix in the pipeat and the resultant gas is admitted to the burner where it is ignited,and so highly heats the sad iron which is seated on the stand 14C abovethe burner. The bafiie 18 serves to check the products of combustion intheir passage to the top of the furnaces and so prevent rapid dischargeof the same, the heat thus being retained longer in the portion of thebody that contains the irons, the effect of which on the said iron beingevident.

Attention is drawn to the fact that the gas and air are drawn into thelower portion of the body of the furnace in order to produce thegreatest heat in said portion where the irons are located, said ironsbeing subjected to the burning flames of the mixed gas and air. Then,the baffle serves as a heat-retarding and radiating device in downwarddirection preventing the immediate escape of the products of combustionfrom around the irons, and preserving the heat of the latter. Then thevents 24 introduce fresh air into the front of said body above the ironsand consequently below the baffle 18 thus cooling said front for thebenefit of the workmen without making any material cooling effect uponthe irons so that the pro-ducts of combustion having their flamesreduced or deadened above said vent-s pass through the perforations ofthe battle and reach the upper portion of the body of the furnacecomparatively extinguished so as to avoid intense heating of said upperportion which otherwise would add to the discomfort of the workmen inthe room in which the furnace is located, it being not-iced that thepresent device is adapted for manufacturing establishments, moreparticularly extensive laundrying.

The furnaces are elevated sufliciently above the floor to be convenientfor the workmen to reach the doors 24 and for that purpose they aresupported on the tops of tables 27. On the sides of the standards ofsaid tables below said tops are the shelves 28 which are adapted forsupporting buckets or other vessels to contain water for cooling the sadirons when so desired.

Attention is directed to the fact that the products of combustion in thebodies 1 are drawn through the pipes 19 and 20 into the pipe or fiue 21and forcibly injected from the latter into the pipe 22 owing to theblower or suction device 23, said pipe 22 opening into the atmosphere orbeing connected with apipe leading to another apartment so that the heatof said products may be further utilized. By this provision also, theproducts of combustion are prevented from entering the work room, andthus the atmosphere of the latter is not fouled nor improperly heated bythe former.

In lieu of previously generated gas supplied to the burner from the pipe11, any combustible fluid may be admitted to said burner the same to beignited at the jet openings 3 and produce a heating medium for the iron,the products of combustion of which after acting on the irons or otherarticles in the furnace being passed off or exhausted, as in the presentcase through the pipe 19.

As air is supplied to the interior of the body of the furnace by ventsor inlets in the side thereof, especially in the present case, in thedoors 2 1, as has been stated, such air mingles with the products ofcombustion and so is consumed, thus intensifying the heat in the furnacewhile also increasing the upward draft in the furnace, thus moreeffectively exhausting the said products and forcibly impelling theminto the pipe 19.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is

1. A sad iron heater composed of a body adapted to support an irontherein, a burner in said body, means for supplying combustible gas tosaid burner, a pipe for the discharge of expended products of combustionleading from said body, an air vent in the body above said burner, asuction device connected with said pipe, a discharge pipe leading fromsaid suction device, a pipe connected with said body for supplying airthereto under pressure, an air holder connected with said air supplyingpipe, and an air compressor connected with said holder.
